Phase-field modelling of microstructural evolution in polycrystalline systems with phase-associated grains has largely been confined to continuum-field *** this study,a multiphase-field approach,with a provision for introducing grain boundary and interphase diffusion,is extended to analyse concurrent grain growth and coarsening in multicomponent polycrystalline microstructures with chemically-distinct *** effect of the number of phases and components on the kinetics of evolution is investigated by considering binary and ternary systems of duplex and triplex microstructures,along with a single phase *** is realised that the mere increase in the number of phases minimises the rate of concurrent grain growth and ***,the effect of components is substantially dependent on the respective kinetic *** work unravels that the disparity in the influence of phases and components is primarily due to the corresponding change introduced in the transformation *** the raise in number of phases convolutes the diffusion paths,the increase in number of component effects the rate of evolution through the interdiffusion,which introduces interdependency in the diffusing ***,the role of phase-fractions on the transformation rate of triplex microstructure is studied,and correspondingly,the interplay of interface-and diffusion-governed evolution is elucidated.A representative evolution of three-dimensional triplex microstructure with equal phase-fraction is comparatively analysed with the evolution of corresponding two-dimensional setup.

Parkinson＇s disease （PD） is a complex neurode- generative disease with progressive loss of dopamine neurons. PD patients usually manifest a series of motor and non-motor symptoms. In order to provide better early diagnosis and subsequent disease-modifying therapies for PD patients, there is an urgent need to identify sensitive and specific biomarkers. Biomarkers can be divided into four categories： clinical, imaging, biochemical, and genetic. Ideal biomarkers not only improve our under- standing of PD pathogenesis and progression, but also provide benefits for early risk evaluation and clinical diagnosis of PD. Although many efforts have been made and several biomarkers have been extensively investigated, few if any have been found useful for early diagnosis. Here, we summarize recent developments in the discovered biomarkers of PD and discuss their merits and limitations for the early diagnosis of PD.

The Tertiary： a proposal for its formal definition

Episodes 2008年第2期31卷 248-250页

Department of Geological Sciences University of Texas at Austin Austin Texas 78712 U.S.A.

The term Tertiary, subdivided into the Paleogene and Neogene, is traditionally used to represent the interval of geological time between the Cretaceous and Quaternary. In the 1990s, however, the Neogene and Paleogene were ratified by the International Union of Geological Sciences as periods/systems of the Cenozoic Era/Erathem, leaving the Tertiary officially undefined. The Tertiary nonetheless remains a formal term that has never been officially eliminated, and its widespread use today implies a long future.

Dear editor,With interest we read the recent article on methemoglobinemia by Chan et al.[1]Through this letter,we would like to add few additional comments regarding methemoglobinemia and its relevance in medicine practice with regards to food *** Chan et al[1]successfully managed their patient of methemoglobinemia and could pinpoint choy sum as the responsible agent,we wonder if there were any more cases of choy sum related to methemoglobinemia detected at the same time in the community?

The Quaternary： its character and definition

The Quaternary, is characterised by the development of widespread glaciations in mid-northern latitudes. As a chronostratigraphic term it has attracted vigorous debate. The Quaternao; as accepted by the International Union for Quaternary Research and proposed by the International Commission on Stratigraphy, begins at 2.6 Ma within a 2.8-2.4 Ma interval of profound change in Earth＇s climate system.

Exporting National Champions:China's Outward Foreign Direct Investment Finance in Comparative Perspective

引用

China & World Economy 2014年第6期22卷 1-21页

作者： Kevin P.Gallagher amos Irwin Global Economic Governance Initiative Boston University 's Pardee School of Global Studies Global Economic Governance Initiative Boston University's Pardee School of Global Studies

We examine the extent to which Chinese development banks have financed the globalization of China＇s ＂national champion ＂firms： specifically, through outward foreign direct investment （OFDI）. We create a database of Chinese fnance for OFDI and compare our results to the existing literature and available data on Japan, Korea and other Asian nations. We estimate the total value of China＇s OFDI finance from 2002 to 2012 at US$14Obn. As a percentage of total OFDI, China＇s lending is roughly three times higher than Japan ＇s, the previous global leader in OFDl finance. We identify two major reasons for China＇s high （31 percent） ratio of OFDl lending to total OFDI. First, China has a greater incentive to give OFDI loans than Japan or Korea ever did because its borrowers are statelowned so it can more easily channel funds to targeted areas. Second, China has a greater capacity to give OFDI loans because it has significantly higher savings and foreign exchange reserves than Japan and Korea.
